Time piece with LED light means

ABSTRACT

A timepiece with LED lights uses a simple light-medium body with a very rough finish to allow light from LED(s) to pass though input-end(s) of the light-medium body and travel within the body and obtain a very even brightness on all surfaces of the light medium that are seen by a viewer. Combined with a milky/frosted front sheet overlay, the light-medium surface can get perfect area illumination effects. The movement for the time display can include analog indicators with a guilt-in light-medium on the top cover to achieve a super slim LED illumination for the time piece. For night light application, the sealed-unit may consist of prong-means and an LED related circuit sealed within a safety standard plastic material and assembled with the night light body to save a lot of cost enable use of all kinds of materials. The invention may also be adapted to an LCD display timepiece.

This application is a divisional of nonprovisional application Ser. No.12/545,992, filed Aug. 24, 2009, which is a continuation ofnonprovisional application Ser. No. 12/292,580, filed Nov. 21, 2008,which is a continuation of application Ser. No. 11/527,631, filed Sep.27, 2006.

BACKGROUND OF THE INVENTION

The subject matter of this application is related to the subject matterof U.S. patent application Ser. Nos. 10/954,189; 11/094,155; 11/094,156;10/667,787; 10/286,871; 10/621,513; 11/094,215; and 11/255,981. Theinventor's prior art U.S. patent numbers U.S. Pat. Nos. 5,926,440,6,158,868, 6,170,958, 6,171,117, 6,280,053 disclose multiple functionnight lights including arrangements for incorporating conductive meansand a time piece. Another prior art U.S. patent, U.S. Pat. No.7,054,233, discloses a light emitting diode (hereafter as LED) modulethat offers a lighting effect for a wall clock, While U.S. Pat. No.6,987,710 by the same inventor as U.S. Pat. No. 7,054,233 discloses anillumination module back surface having reflective properties to allowlight beams to reflect toward the interior of the module and out fromthe front surface (see, the Abstract, line 7 to line 9, and the detaileddescription stating that “The back side of reflectors 38, 48 or 78 couldalternatively be engraved to provide multiple raised surfaces, such aspoints, bumps, protuberances, or the like. FIGS. 14 and 15 illustratesurfaces 86 and 87, respectively, created by dot engraving techniques”).Such an illumination module is very expensive to make compared with thecurrent invention. The current invention uses light medium having arough surface surrounding the medium to cause all light beams to travelwithin the light medium. This rough-surface treatment has more diffusioneffects than the prior structures having a reflective optics property.Furthermore, the prior art seeks to control light beams only “out of thefront surface,” which is mission impossible. The current inventionallows light to be emitted out to the viewer in all directions throughthe rough-surface of the light medium with the option of having somelight beams blocked out by the housing so as to obtain desired lighteffects. The above-cited patents do not teach a milky/frosted frontsheet to enable an illumination module to obtain the best light output.It is impossible to make a commercial items without this milky/frostedfront sheet on top of the illumination module.

The inventor also has other prior U.S. patents, including U.S. Pat. Nos.6,811,278, 6,601,964, 5,926,440, 6,158,868 directed toelectro-luminescent lighting arrangements.

A first feature of the current invention involves a variety ofarrangements of the light medium, including the light-medium beinglocated between the front lens and timepiece movement, which optionallymay incorporate a cosmetic dial face means or dial marking directlyapplied to the light-medium surface by silkscreen or a sticker usingconventional market available skills. Alternatively, the light mediumcan be located on a part of the timepiece movement, such as a top coverof the movement, to provide a relatively slim device.

A second feature of the current invention involves adapting a verysimple optic theory to the light medium for time piece illumination,which is similar to the optic theory used in notebook computer screens,which is in contrast to the “back surface with reflective property”arrangements illustrated in FIGS. 14 and 15 (86) and (87), of theabove-cited U.S. Pat. No. 7,054,233, which require a complicated opticslens. The current invention light medium simply uses a rough surface ofthe light medium to obtain a very even illumination on the whole unitsurface.

The third feature of the current invention is to incorporate therough-treatment light medium with a front milky or frosted sheet toprovide perfect illuminating effect with super low cost while meetingall safety standards.

The fourth feature of the current invention incorporation of prong-meanswith an LED circuit and LED(s), which are sealed into a sealed-unit thatmeets the safety standard for V-0 grade under certain housing materialsand thickness, so that other night light material can be used outsidethe sealed-unit, including any combination of paper, plastic, poly,chemical resins, pottery, porcelain, glass, mud, wood, bamboo, and/ormetal for any other parts. Such an arrangement will still meet allsafety standards because the other material(s) do not touch any hotwires.

The fifth feature of the current invention is that the timepiecemovement has desired parts which may include LED(s), a light medium aspart of the movement, an LED circuit, control means, and sensor means toenable the whole night light to have super slim dimensions. The size ofthe built-in light medium cover and movement of the lower housing can bevariable depend on the different applications for final product size.For example, the light-medium top cover can be bigger or smaller orequal in size to the timepiece movement lower housing to let the finalproduct look pretty.

The sixth feature of the current invention involves the night lightdevice having multiple functions such as a night light function, colorchanging functions, multiple lit-areas, a plurality of receptacles,switch means, sensor means, as well as a time piece with either ananalog display or LCD display, weather station display, project display,and/or liquid device for desired functions and light effects to meetmarket requirements.

The seventh feature of the current invention is that the movement canhave its desired power source from a 10V to 250 Volt AC wall outlethaving an appropriate frequency, or/battery power or solar power tosupply the time piece operation. The power source for the movement andother functions can be same power source as the light or a differentpower source depend on market requirements.

The eighth feature of the current invention is that the lightarrangement can be designed to have an analog arms cover. This willprovide the whole dial face with very bright illumination to read thetime message. This also is applicable to an LCD display unit by adding aback holder with light illumination.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIG. 1, a time piece (19) with LED light means has amovement (28) and sealed-unit (18) inside a housing (2). The sealed unitmay have any combination selected from LED(s), an LED circuit, controlmeans, sensor means, switch means, and prong means. Use of a sealed unitis good for safety reasons because prong means (9) and the LED circuit(not shown) and LED(s) have electric contact with live wires (highvoltage) and therefore need to meet the UL safety standard which hasvery strict material requirements. It is very safe to put all theseparts into the sealed unit that meets the flammability safetyrequirement. All the rest of the parts, such as movement, light-medium,front sheet (milky or frosted treated sheet), or other housing elementsare not required to meet the safety standard if all parts in potentialcontact with live wires are sealed by a required material. This is oneof the features of the current invention. It will help resolve productdesign and cost saving issues.

As also shown in FIG. 1, the arms (5) (6) (7) are securely installed onthe movement (28) axis to provide an accurate time display to viewer.The prong means on the back of the housing (2) may use a fixed angle orswivel angle construction from conventional available skills. Thehousing (2) has a sensor means (1) and extra light means (8) on adesired location of the housing (2) to activate the LED(s) and provideextra illumination to the floor with stronger light beams.

FIG. 2 illustrates a second preferred embodiment having a dial face (35)with color changing effects. The time piece (30) has a second lightmeans on a lower portion to provide a second lit-area of the time piece(30). The second lit area is disclosed in co-pending U.S. patentapplication Ser. No. 11/255,981.

FIG. 3 illustrates a third preferred embodiment having a dial face (32)and housing (33) having multiple areas with the light effects includingproviding the dial face (32) with surface illumination and the housing(33) with a lot of fiber optics that appear as dots arranged to form anilluminated logo, name, or other shape or configuration. The timepiecemay be a wall clock, alarm, or night light with analog movement, oranother timepiece corresponding to including timepieces corresponding toconventional market available models and options but with addedillumination.

FIG. 4 shows details of the construction of a preferred timepiece withLED light means. The movement (80) has installation points (8A) (8B)(8C) (8D) to allow the movement (80) to be securely assembled to thelower housing (81). The prong means (8X) (8Z) are inserted into thehousing slots (8Y) (8Z′) to allow the night light to get electric powerfrom the power source (illustrated as a 110 Volt AC, 60 hz power sourcefrom a home wall outlet of the type found in North American). The lowerhousing (81) has a movement compartment (8G) to allow movement (80) tofit in tight. The lower housing (81) also has a wall arrangement toenable the inner space to receive movement (80), light-medium (K8), LEDsealed unit (82), prong means (8X) (8Z) at ideal locations. Thelight-medium (K8) has holes (I8) (L8) (8U) and related screws (8J) (8M)(8T) to allow the light-medium to be fastened on the lower housing holes(8E) (8H) (8X′). The light-medium (K8) has a plurality of input-endssuch as the right one (8V) which can allow the respective LED (8V′) tobe installed within the input-end (8V) to allow majority of the LED(8V′) light beams get into and travel with the light-medium (K8) andallow a viewer to see the brightness of the whole surface of thelight-medium unit. The light-medium (K8) is made of plastic materialwith a roughening treatment on its surface by sand-blasting or atooling-texture process (or equivalent skill from conventional marketavailable skills). The rough surface will prevent the majority lightbeams from passing through the edge and cause diffusion of the lightbeams traveling within the light-medium without large losses to theoutside. Because the majority of light beams travel within the medium, ahigh degree of brightness is achieved. This effectively converts the LEDpoint source to a smooth area illumination. This effect is enhanced byproviding a milky or frosted front sheet (83) to overlay on top of thelight-medium (except in the area of the clock face) in contrast to theabove-cited U.S. Pat. Nos. 6,987,710 and 7,054,233 for wall and alarmclock applications, which at best might achieve the same effect if allfive sides of the illumination module were to be sealed by mirror likereflector materials without any light beams been leakage from the fivesides. Such an arrangement would require a lot of labor and is not aspractical as the present invention with respect to mass production andmeeting standard quality requirements. The current invention has ofsimplicity, uniformity, easy operation and low cost, and less laborintensive construction.

The arms (8S) (8R) (8Q) installed on the movement (80) axis (8C) asnormal installation to show the time message to viewer. The armsprotective cover (84) preferably is clear to allow viewers to see thearms' location to know the time. An upper housing (85) tightly coversthe lower housing (81) to prevent other parts from loosening or fallingapart during a drop test on the time piece.

FIG. 5 is a side view of a preferred embodiment. The timepiece has amovement (40) disposed within the back housing (46′) with an axis (45)to install the arms (not shown). The movement (40) has one thicklight-medium (44) which accommodates entire LED(s) (49) within thelight-medium so all light beams will get into the light-medium (44)without leakage to outside. The light-medium (44) have a very roughsurface by made by sand blasting or tooling, or an added milky compoundor other conventional market available skills to make it very rough onits entire surface as discussed above. The light beams travel within thelight-medium and quickly back and forth to cause the bright spot of theLED to change from a point light to a surface light. In front of thelight-medium is a milky or frosted front sheet (not shown) which canmake-up for any bright and dark areas to provide perfectly smoothillumination. By these two treatments, the dial face will have perfectbrightness on every point of the entire dial face surface. A clearprotective cover (43) for the arms of the clock is tightly fit withinthe front housing (42) (46) and assembled to the back housing (46′) andfastened by tightening means selected from screws, solvent, sonicsealing, glue, rivet, or other equivalent skills from the art. The prongmeans (48) and LED (49) in the above-described sealed unit to enhancesafety relative to other models in which all electric components areexposed to air and which therefore are more costly than the presentinvention with its sealed unit. In models without the sealed unit, allmaterials have to be V-0 Flammable grade to pass UL standard, have avery thick wall thickness, and use materials purchased from certain ULlisted suppliers. The axis (45) on which is installed the second,minutes, hour, or time setting indicators needs to be long enough toallow the added light-medium thickness to properly fit on top of themovement cover and under the arms. A decorative dial face may be madeusing a stencil or milky/frosted front sheet with printing, logo, ormarking on top of the light-medium unit. The movement has to bespecially made to have a longer axis than other conventional time piecemovements.

FIG. 6 shows an alternative embodiment in which not only does the dialface (67) have illumination, but other exterior housing areas (62′) (62)have illumination too. The rest of the parts are similar to those shownin FIG. 5. In FIG. 6, the extra LED(s) are extended from the sealed unithousing by conductive wires to spaces (62′) and (62). These two spacesare filled with certain material such as opaque poly material so as toallow light to pass through and also have a certain percentage of lightbeams travel within the material to make a very good light effects. Thisembodiment includes a plurality of illuminated areas of the time piece,not only at the dial face and housing, but also other areas selected fordecoration or value-appearance purposes. The axis (68) on which isinstalled the second, minutes, hour, or time setting still needs to belonger enough to allow the added light-medium thickness to properly fittop of the movement cover and under the arms. A decorative dial face mayagain be made using a stencil or milky/frosted front sheet withprinting, logo, or marking of designs at an appropriate position on topof the light-medium unit. The movement has to be specially made to havea longer axis than other conventional time piece movements.

FIG. 7 shows a round movement (7 a) which has its power source selectedfrom a wall outlet power source such as a 110-250 Volt AC outlet with anappropriate frequency. Alternatively, the power can be come from a drybattery or batteries, or the power can be obtained from a solar panel orother energy saving device. The movement has at least one adjustmentfeature to allow people to set the time or alarm, or adjust music,volume, recording, or a snooze function by means of a switch, sensor orother component. The functions provided by the adjustment feature mayinclude any functions available from conventional market availablefunctions. The movement also has a lot of terminals to allow people toadd multiple functions when the proper device is connected to thefunction terminal ends (7 c).

FIG. 7 is a right hand side view showing an embodiment in which thelight-medium (6 g) is part of the movement. The cover of the movement (6e) has light-medium functions which allow the LED(s) to be installed onthe input-end (6 f) and cause the light to travel within thelight-medium (6 g) and provide a very even brightness on its entiresurface. This will cause the entire time piece to have a more slim andcompact size by reducing the movement cover thickness relative to otherembodiments. Thickness is a very important consideration in meetingmarket requirements. The axis (6 a) passes through the light-medium (6g) center hole to enable installation of the timepiece arms. Thebuilt-in sealed unit which has the LED(s), LED circuit or other requiredelectric components, and power source to make the LED(s) turn on underpredetermined timing for desired functions and periods of time. TheLED(s) (6 b) (6 d) may be installed on the sealed unit housing orconnected within the sealed unit housing by conductive wires anddisposed within the light-medium walls.

FIG. 7A shows a round movement having a light-medium as part of the topcover with axis hole. The movement lower housing has diameter “d” andupper light-medium cover has diameter “1×d” with desired LEDinput-end(s) extended from an edge or desired location. FIG. 7B shows around movement that has the light-medium as part of the top cover withaxis hole. The movement lower housing has a diameter “d” and the upperlight-medium cover has diameter “1/N×d” (N can be any number) withdesired LED input-end(s) extended from an edge or desired location. FIG.7C also shows a movement that has the light-medium as part of the topcover with axis hole. The movement lower housing has diameter “d” andupper light-medium cover has diameter “N×d” (N can be any number) withdesired LED input-end(s) extended from edge or desired location. FIG. 7Dshows a rectangular movement that has the light-medium as part of thetop cover with axis hole. The movement lower housing has diameter “S×S′”and upper light-medium cover has diameter “L×L′” with desired LEDinput-end(s) extended from an edge or desired location. The rectangularshape movement may have additional features such as a pendulum, alarm,bell, music, recorder, vibration, flash light or other featuresavailable from the marketplace.

FIG. 8 shows a preferred movement (50) which is the most low cost unitcurrently available. The lower housing (50′) has movement componentsincluding an electric-coil (5 a), output terminals (5 b), axis (5 c),gear sets (5 d), battery “+” terminal (5 e), battery “−” terminal (5 f)and a quartz kit (not shown) to make the movement have good accuracy andallow timepiece arms (not shown) to show the time message and functionsto consumers. The entire space of the most low cost unit has plenty ofempty space as illustrated. The current invention uses the empty spaceto install the LED(s), LED circuit, and some necessary control means andparts (may including prong means) within the lower housing (50′) andmake a new top cover with axis hole and having light-medium properties.This will allow the whole movement to have built-in LED light functions.

If the built-in LED light device is powered by a movement battery (thiscase the movement and LED light device are powered by same battery powersource), the LED light will only turn on after a sensor device has beentriggered for short time, so that the LED is activated by the motionsensor to turn on for a limited time period.

If the built-in LED light device is connected with a wall outlet powersource (for example a 110 Volt AC 60 Hz source) through prong means(i.e., the movement is powered by the battery and the LED device ispowered by the wall outlet power source), then the LED light device canalways be “On” because the power source is unlimited energy relative tothe LED device, which uses only 0.3 to 1 Watt of power. Some designs mayeven have a very strange power source such as an LED light device andmovement both connected with the wall outlet power, although such adesign might be disadvantage because it will cause the movement to stopwork while the prong or conductive means are separated from the walloutlet power source such that each time the termination happens, theconsumer has to adjust the time again. For example, if the clock isinstalled in a bathroom, when one wants to use a hair dryer, the clockwould need to be unplugged, after which the time would need to beadjusted again, each time the clock is unplugged from the wall outlet.To alleviate the unplugging problem, the multiple function time piececan have the receptacle (1) on front of the time piece as shown inFIG. 1. The receptacle is preferably grounded to safely accommodate alldifferent electric devices such as a hair dryer, electric tooth brush,electric tooth water jet . . . which may have a grounded prong design.

FIG. 9 shows an embodiment with a liquid crystal display (hereafter asLCD) for displaying messages. The LCD (90′) is made glass which can betreated to provide a very rough surface according to the principles ofthe invention. This specially made glass with rough surface on theexterior of LCD (90′) has a thickness that allows the LED(s) (92) (92′)to be disposed within the glass thickness on the input-ends (99) (99′).The other parts LED sealed unit (91), prong means (97) of fixed type orswivel type, a back holder (94), a light-medium (as an alternative tothe rough surface on the LCD glass, the light-medium can supplybacklight to the LCD as discussed above). The LCD weather stationmessage display may display messages including but not limited totemperature (98′), time (98″), date (98′″) or any other information suchas humidity (not shown), calendar (not shown), month (not shown), orother message available from conventional market. The built-in LCDdot-matrix display has an LED light-medium to make it glow. Thelight-medium can be an LCD glass or separate plastic piece as long as itis adapted by means of a sand-blaster or other conventional skills tohave a rough surface to obtain the desired light medium properties. TheLCD display can be fully transparent or the semi-transparent type whichdoes not affect the LED light-medium too much.

FIG. 10 timepiece with a projected image (2 a) seen by a viewer. Theimage (2 a) is projected from the lower dial face (2 g) which has atimepiece movement (not shown) and LED sealed unit (2 e) as in thenormal timepiece arrangements described above, but with a thick liquidoptics device (2 b) to transfer the lower dial face's message to theviewer face (2 a) with correct orientation for hour, minute, and secondarms and marking The thick liquid optic device (2 b) may have a lot ofminiatures with special treatment such as a magnetic base to makemagnetic reaction with the second arm so a turtle (2 c), by way ofexample, will stick with the second arm for each second to move. Theturtle (2 c) may have tiny wires to connect with duck 1 (2 c′) and duck2 (2 c″) to provide a very valuable appearance to all viewers, andespecially for kids. The swivel prong means (2 d) are good because thistimepiece can act as a desk top clock or night-light clock for twoapplications and thereby provide the consumer with a multiple purposetimepiece.

FIG. 11 shows an analog time piece (110) having at least 3 arms (11 g)(11 h) (11I) to show the time message of hour, minute, second to aviewer though the protective cover (11 a). The protective cover (11 a)made of clear plastic, which may have texture or a milky/frosted surfaceon the area which is not in front of the dial face (11 d). The textureor milky/frosted surface treatment will let the cover (11 a) havelight-medium properties so as to allow the light beams to travel withinthe cover and a majority of light beams to be seen on the cover surface.This kind of light beam arrangement is sufficient to offer goodillumination to the dial face (11 d). At least one LED (11 k) (11 k′)(11 k″) is disposed within the cover (11 a) on its grooves, openings,windows, cut-outs to allow the LED light beams to travel within thecover material. This arrangement can be used to cause a brighter ring(11M) (11M′) to be seen and make the dial face (11 d) have very goodbrightness to enable the time message to be easily seen. The cover (11d) has several latch means (11 e) (11 e′) to allow the cover (11 d) totightly joined together with lower movement housing (11 c). The movementhas a lot of grooves and/or holes to allow assembly with the cover (11d) or with the other housing parts (not shown). The LED light means hasconductive means to connect with the LED circuit, and control means andprong means to make the illumination.

FIG. 12 a cover 120 with grooves (122) (122′) (122″) to provide space toaccommodate LEDs (121) (121′) (121″) and enable the light-medium's cover(120) to have good brightness to cause the inner dial face to bereadable while needed.

As shown in FIG. 13, the sealed-unit (S2) (S12) (S22) has pre-designedopenings (S2′) (S12′) (S22′) to provide a universal type of thesealed-unit (S2) (S12) (S22) that can fit into the opening (S2′) (S12′)(S22′), which can use the conventional market method to fasten with thebase (S1) (S10) (S20), and which may assembled with the night light by ascrew (S23) (S24), welding, sonic sealing, glue, solvent, a rivet, alatch, or equivalent fixing-means known to those skilled in the art toallow the sealed-unit be fixed position. The sealed-unit (S2) (S12)(S22) preferably uses a plastic with certain thickness to pass the94-V-0 flammable grade to meet the safety standard while all otherhousing parts (S1) (S10) (S20) are without any limitation as tomaterials because they cannot touch live wires. The base (S1) (S10)(S20) can be any shape, configuration, design, curvature, thickness,material, and/or dimension, with built-in or separated receptacle means.The sealed-unit has LED related circuit, control means, and prong meansdisposed within, and can be designed for a super slim and wider unit ora thicker but smaller unit, depending on the market requirement. Forconvenience, the unit can also be designed to fit into different baseshapes such as a boat shape (S1), tube shape (S10), or rectangular shape(S20) for different night light applications.

The boat base (S1) has an opening (S2′) to allow the sealed-unit (S2) tofit into the space. The sealed-unit (S2) has an LED related circuit (S8)and its components (S9) and prong means (S7) (S7′) are sealed within thecase (S2). The top of the case has two LEDs (S3) (S4) which areconnected with the inner circuit (S8) so that all of the LEDs' electriclegs can be touched by test equipment to make sure a kid's finger willnot touch these live wires and cause dangerous condition. The LED (S5)can use the conductive wires (S6) to extend away from the unit's housing(S2) for other illumination arrangements.

The LEDs (S3) (S4) also fit into the base opening (S3′) (S4′) and a wall(S2″) will cover the LEDs after assembly with the base housing. Afterassembly, the LED light beams can pass through the base's opening area(S) to provide good light effects to the upper display unit.

The tube base (S10) has an opening (S12′) to allow the sealed-unit (S12)to fit two or more LEDs at a desired position and orientation, and awiring arrangement that can allow the light beams to be emitted out fromthe base top opening (S18) and lower window (S18′) for desiredillumination.

The rectangular base (S20) offers a special surface light arrangement.The LED spot light beams through a light-medium (S28) to allow the LEDlight beam to travel within the light-medium (S28) and a majority oflight beams to be seen by a viewer from the light-medium (S28) surface.The viewer will not see any hot spot of LED light brightness but willinstead see a very soft and even area light for special illumination.The rectangular base (S20) has an opening (S22′) to allow thesealed-unit (S22) to fit tightly therein and be secured with glue,solvent, or other adhesive means, sonic means, welding means, latchmeans, or hook means. The LED will fit into the light-medium's thicknessto get the best result.
